The times. (Owosso, Mich.) 1882-1897, 1887-06-03

A company has been organized TO
use the water-power from The falls at
Shafhauscn, ON the Rhine, to manu-
facturc aluminium according to the
Cowles method.
A German writer has recently noted
that of all human hair red hair is the
coarsest and blonde hair the finest.
The diameter varies from 1850 to l.
600 of an inch. He also notes that in
four heads of equal size that with red
hair was about so, 900 hairs; with black
100000; with brown 100000; and with
blone 100000.
The common laundry practice OF
bluing clothes illustrates very COM
mon law of color. Blue and yellow
are what are known as complementary
colors-that is, together they form
white. Hence the addition of minute
quantities of indigo, Prussian blue, or
other blue material to the linen COM
pletely neutralizes the natural yellow
tint, and gives the clothes clear
white appearance.
The London Lancet records a re-
markable case of transmission OF dis
ease from mother to child. The wo-
man was admitted to the hospital sui
fering with acute pneumonia the
left lung already four days advanced.
The temperature was 1886 degrees
Fahrenheit. That evening she was
delivered of child, and ultimately
recovered. The child, however, died
twenty-four hours later with every
symptom of pneumonia. The post
norton examination showed that the
whole of the left lung of the child was
also affected, and had undergone the
well-known acute pneumonia CONSOLE
dation. This is believed to be the first
case recorded of transmission of this
disease.
The physical laboratory at Beloit
college is connected by telephone with
the clock at the astronomical observ-
atory in order to time accurately the
experiments, The two telephones are
placed in the circuit. with two receiv-
ers at each end. If one receiver DE
placed at the ear, the ticking of the
clock can be distinctly and sharply
heard and counted. If, however, both
receivers be used at the same time, one
at either ear, no sound is heard
through the telephone, but a sharp,
painful tap is felt at the base of the
brain, and the whole Uranium seems to
reverberate. No suitable explanation
of the phenomenon has as yet been
offered. mn 8l
At Megrin, Canton of Geneva,
Switzerland, there is q series of wells
which possess. peculiar barometic prop
critics. The wells are deep and tightly
covered at the top except for small
vent. This air-hole the air enters or
is driven out, often with sufficient
force to produce whistling sound,
according as the conditions of the
atmosphere may change. If any light
article, as feather, be thrown over
the vent, if the barometer is falling it
will be blown away, if the barometer
is rising, with consequent increase of
pressure without, the feather or other
light matter will be drawn to the open
ing. OF course the causes of these
phenomena are the difference of pres
sure within and without the wells,
induced by the changes in the at
mosphere. Fk fH aA ff SFW

The Scientific American prints some
curious calculations concerning the
electric lamp. Many persons have the
impression that the interior of glow
lamp was place that was empty of all
air particles. Maxwell has shown that
in small cube 100000 of an inch
there would b1 100,000,000 molecules
of ordinary air; SO that, in a cubic
inch of air, there was at least 100000
0O0, 900, 900, 900 molecules. In a Swan
lamp, when exhausted to one-millionth
of an atmosphere, there remained
some 400, 900, 900, 900 molecules of air.
AS it takes about ten days to count a
million, it would take at least 10000
years of continual counting to count
the number of molecules in such a
'vacuum.
